2 Claims. (Cl. 15..244)

This invention appertains to paint applicators, and more particularly to paint applicators of the so-called roller type.

In all paint rollers with which I am familiar, a handle is provided having a laterally extending shaft on which is journaledan expanding mandrel or cylinder for snugly receiving and holding-a paint applying sleeve. This sleeve is usuallyY formed from an outer member of sheepskin or a simulation thereof,.i; e., a fabric having a pile. The fabric or sheepskin is reinforced byV an inner rigid core or liner formed from a thermoplastic or a fibrous (cardboard) material. The sleeves are difficult to clean and thepaint applying pile soon becomes matted. Further, if a seam is employed on the sleeve to join the edges of the fabric, such seam tends to.. mark the surface being painted.V Obviously, the expanding mandrel, its journals, the reinforcement for the l-sleeve,etc., result in an expensive, inadequate structure.

It is, therefore, one of the primary objects of my invenf tion to provide an inexpensive paint roller in which the expanding mandrel, reinforced sleeves, etc. are entirely eliminated.

Another salient object of my invention is to provide a paint applying roller formed from rubber foam, sponge rubber, or the like, having an unbroken paint applying surface, whereby marking of the surface being painted is prevented. i

A fur-ther object of my invention is the provisicn of a paint roller formed from a cylinder of paint absorbing material, such as rubber foam, so that as the cylinder is rolled over a surface with a desired pressure the paint will be effectively and evenly applied to a desired surface.

Another further object of my invention is to provide a paint roller formed from a solid cylinder in contrast to a sleeve, the cylinder being formed from rubber foam or the like mounted for free turning movement directly on the shaft of the handle, so that the use of expanding mandrels and the like is entirely eliminated.

A still further object of my invention is to provide a paint applying roller which can be readily cleaned by alternate soakings in detergents and the like, and by a wringing out process.

A still further object of my invention is the provision of means for sealing the ends and the wall of the bore of the paint applying roller so that leakage of paint from the ends and bore of the roller will be prevented, and whereby the paint can be readily pressed from the roller onto a desired surface from the periphery of the roller only.V

Another further object of my invention isito provide novel means for rotatably mounting the resilient and compressible roller directly on a shaft carried by a manipulating handle.

A further salient object of my invention is the provision of novel end caps forming hub plates for receiving and clamping the resilient compressible rubber foam roller therebetween and on the shaft for free turning movement,

2,810,924 Patented Oct. 29, 1957 fice 2 whereby the roller can he easily rolled over the paint containing tray and the surface to be coated.

A still further salient object of my invention is to provide a novel arrangement of end caps or hub plates for the roller, Yso that upon adjustment of the hub plates toward one another, the roller will be slightly compressed longitudinally and whereby the peripheral edges of the roller at its opposite terminals will be Slightly bowed or curved to preventmarking of the surface being painted by abrupt edges.

With these and other objectsl in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter more specifically described and claimed, and illustrated in the accompanying drawings, in which drawings,

Figure l is` a longitudinal sectional view throughk one form of my novel paint applying roller;

Figure 2 is a transverse sectional view through the roller taken on the line 2 2 of Figure 1 looking in the direction of the arrows;

Figure 3 is a side elevational view showing how the roller can Vbe cleaned by a wringing out process;

Figure 6 is a front elevational view in partial section, showing one improved, mounting for my novel roller.;

Figure 7 is an enlarged longitudinal sectional view. through the roller, illustrating the means. for initially mounting the roller on the shaft of the paint appliance, and

Figure 8 is a detail end elevational view illustrating one of the novel end caps or hub plates.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter R generally indicates my improved paint roller, and this roller is formed from a substantially solid cylinder of paint absorbing material, preferably rubber foam or synthetic rubber foam, and more particularly, a roller made from a polyurethane compound. The cylinder or roller R is provided with a centrally disposed longitudinally extending bere 10 through which the shaft of a paint roller outfit or appliance A extends.

The roller when mounted on a shaft, as will. later appear, for free turning movement is saturated with paint in the accustomed manner, i. e., the roller is rolled over a pan containing paint and the foam rubber will pick up and carry a certain quantity of this paint. Upon the rolling of the roller R over a surface to be covered, the paint will be applied in an even coat on such surface without any marks in view of the factv that the surface of the roller is continuous and unbroken by seams or the like. Due to the porosity of the roller,y a quantity of paint will be picked up by the roller and the paint can be applied as a coat when pressure is applied to the roller and to the surface being coated. In actual practice, the thickness of the coat can be controlled by varying the pressure of the roller on the surface being coated.

Besides the advantage of producing an inexpensive roller, my roller has the added advantage of being able to be quickly and thoroughly cleaned, and thus the roller can be used over and over again with different. colors and shades of paint; The roller can be easily cleaned in view of the fact that the same is formed from foam rubber, and hence, the roller can be wrung out in the same manner as a fabric garment, and the roller can be washed directly under a faucet or can be soaked in a detergent or paint solvent liquid and then wrung out and washed in soap and water under a faucet and wrung out. Great stress is laid on the fact that the roller is formed substantially This can be accomplished in varying manners, such as by forming a Vsealing skin on the ends of the rollerand on Ythe bore of the roller, leaving only openrpores on the periphery of the roller. Y Y, Y

Y `As illustrated in Figures 4 and 5, the endsof the roller 'R'.can be provided with a sealing coat 11 of any 'desired fmaterial having an affinity for synthetic foam rubber. A Vsimilar coating 12 can be applied to the wall of the bore 10. "The coating can be neoprene and the neoprene can lbe sprayed on the ends ,of the cylinder and onto the wall of the bore, and,.obviously, the neoprene will not materially affect the resiliencyror compressibility of the roller. Other steps can beV taken to Vseal the ends of the rollers, such as thin discs of thermoplastic secured by adhesive or the like to Vthe terminals of thecylinder.

Y .Now referring more particularly to the paint roller outlit or appliance A the Vsaine includes'a longitudinally extend-V ing shaft 15 for rotatably supporting the roller R.

The shaft 154 is preferably formedas an integral extension of a shank 17 carrying a manipulating handle 18. The'handle 18 is disposed transversely of the shaft 15 and is spaced therefrom.` The shank 7 is connected with the shaft 15 by a gooseneck portion 19. Y'

The shaft 15 adjacent to,'but spaced from the gooseneck portion 19 has rigidly secured thereto astop collar 20,'thel purpose of which will later appear and the outer end ofthe shaft is provided with an internally threaded bore 21. V

The mounting for the roller R'includes a pair of like end caps or hub plates 22 and 23 and in assembling the paint applianceQthe end cap or hub plate 22 is slipped on the shaft 15 against the shoulder 20 after rwhich the roller R is placed on the shaft. `The end cap 23 is then applied Vto the shaft and'is held thereon Vby a machine screw 24 threaded intothebore 21.

Y'Theend'caps or hub plates 12 and 13 each include a disc shaped body portion 25 which is inwardly and cen- Y trally dished.V Formed on the body portion 25 is an in-` wardly directed peripheral ange 26 of. an annular formaftion andV this flange canV be slightly tapered inwardly Vtoward 4its peripheral edge.. Bushings 27 are rigidly set into the `body portions 25V and these bushings form bearings for rolling Contact with the shaft 15. Y Considering that the parts of the paint appliance A vented. Where the ends of the roller R are sealed to prevent leakage of paint therefrom, the curving of the ends of the roller is of the ulmost importance, in that, g

the skin or 'sealing means will not contact the surface being painted. Y

By forming the end caps or hub plates 22 and 23 of a less diameter than the diameter of the rollerY R and by providing the inwardly directed peripheral flanges 26, the ends ofthe roller are pressed inwardly Vbringin about the Ydesired curving of the roller. 'e

V(Dbviously, equivalent means can be utilized for the set screw 24'to adjustably hold the end caps or hub plates Y Y in clamping compression engagementwith the roller.

The bore of the Vroller is preferably of a slightly greater diameter than the diameter of the shaft 15 so that the roller'will turn freely with the end caps or hub plates 22 and23 and these plates form the bearing for the roller.

Various changes in details `may beVV made without departing from the spirit or the scope of this invention, but what I claim as new is:

Y 1. An appliance for painting and like operations comprisingV a shaft, a paint applying roller. fonmed from compressible, resilientematerial having pores, said roller Y yhaving an axially disposed longitudinally extending bore receiving the shaft, said roller having its bore and terminals sealedto prevent leaking of paint therethrough, and means gripping the terminals of the roller freely rotatable on the shaft curving the periphery of the roller 2. An appliance for painting and like operations comprising a shaft, a manipulating handle extending transfversely of the shaft, means connecting one end of the shaft with the hand1e,a stop on the inner end of said shaft, a paint absorbing roller formed from compressible, resilient material having a longitudinally extending bore Y receiving the shaft, end caps of a less diameter than the roller gripping the terminals of the roller, each of said ly rotatable on the shaft with one end cap engaging the stop, and adjustable means on the outer end of the shaft engaging the other end cap for moving said last mentioned end cap toward the end cap engaging theY stop, whereby theV roller will be slightly compressed longitudinally and the ends of the rollerY pressed inwardly curving the periphery of the roller at its terminal edges.

have Vbeen assembled on the shaft 15 as heretofore described, and the screw 24 is turned into the bore 11 (it being understood that a washer 28 is interposed between the head of the screw V24 Vand the bushing 27 of the end cap or hub plate 23), then upon tightening of the Y screw the anges 26 of the end caps or hub plates 22 and Y23 will be pressed into the'opposite ends ofthe roller Y Y R and the roller will be slightly compressed longitudinally. VThe compression of the roller longitudinally will Vbow or curve the periphery of the roller at its end edges, t as best'shown in Figure 6 and indicated by the' reference character 29. The'curvature of the roller RY at'v its ter- 'minals' isfirnportant to this invention, in that, abrupt VYedges at its ends'Y areeliminated, and consequently, Yas

'the'roller is rolled along a surface during the applica-V tion of Vpaint,'tl1e marking of such 'surface will'be pre- References Cited in the tile of this patent i UNTTED STATES PATENTS 903,670 GermanyV Feb. 8,
